Title:

POLYESTER TEREPHTHALATE-CO-SEBATE RESIN AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2018/045929

Kind Code:

A1

Abstract:

A polyester terephthalate-co-sebate resin and a preparation method therefor. The structure of the polyester terephthalate-co-sebate resin satisfies the following relation formula: Sδ(hydrogen on conjugated carbon chain)/Sδ(hydrogen on saturated carbon chain 1.2-2.4)=0.1-0.35, where the Sδ(hydrogen on conjugated carbon chain) is the total area of peak integral of hydrogen on the conjugated carbon chain in a 1H NMR spectrogram, and the Sδ(hydrogen on saturated carbon chain 1.2-2.4) is the total area of peak integral of hydrogen on the saturated carbon chain in the 1H NMR spectrogram with the chemical shift of 1.2-2.4 ppm. When the polyester terephthalate-co-sebate resin is prepared into a thin film with the thickness of 25±1 µm, the water vapor permeability of the thin film is 100-1,500 g/m2/d, and the moisture permeation property is good.
